HYD-ROCARBON-FURNACE SPECIFICATION forming part of Letters Patent No. 251,989, dated January 3, 1882. Application filed September 16, 1881. (No model.) k

To all whom it may concern:

Be itknown that I, MICHAEL ZEGK,Of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain Improvements in Hydrocarbon-Furnaces, of which the following is a specification.

This invention relates to improvements in furnaces adapted to the burning of crude petroleum and other liquid fuel; and it consists in certain novelties of construction, which 1 .will now proceed to describe.

Ofthe accompanying drawings, formingpart of this specification, Figure 1 represents a side elevation of a locomotive provided with improvements embodying my invention, the firebox and a portion of the tender being repre sented in sections. Fig. 2 represents a section on line y y, Fig. 1. Fig. 3 represents an offset section on lines a: a Fig. 1, and 00 m, Fig. 2, the last two figures being on an enlarged section.

The same letters indicate the same parts in all the figures.

In illustrating my invention I have shown it applied to a locomotive; but it will be understood that it is applicable to other kinds of engines, suchas stationary, marine engines, &c. In the drawings, A represents the fire-box of a locomotive, which is partially separated by a perforated partition, B,.more particularly described hereinafter, into a primary combustionchamber, 1, and a secondary combustion- Q chamber, 2, the partition B. being provided with slots or perforations, through which the smoke and other products of combustiom can pass from the chamber 1 to the chamber 2 on their way to the smoke stack.

0 represents an oil-tanklocated on the tender, and provided with pipes D D leading to any desired number of branch pipes, D, entering the sides of the primary chamber 1 of the fire-box. The branch pipes or jets D may be arranged in any desired manner with reference to the chamber 1.

E represents apipe entering each oil-pipe D, and adapted to conduct steam from the boiler F into the oil-pipes. The pipes E enter the pipes D in such direction that the steam will force the 'oil through the pipes D and branches D into the fire-box in the form of spray, the

steam mingling with the oil and ejecting it forcibly from the jets D into the fire-box. The oil is thus finely subdivided, so that it is in the best condition for combustion. When the spray of oil and steam is ignited the steam assists in destroying the carbon in the oil, and thus prevents in a measure the formation of lamp-black. I further assist the combustion by mingling atmospheric air with the oil and steam at thepoint where said oil and steam enter the fire-box. To this end the branches D, through which the spray of oil and steam enters, are surrounded by annular airpassages H, which are ofsufficient length to cause the air passing through them to be heated by contact with the steam-heated branches D before entering the fire-box. By the employment of air, as last described, the consumption of carbon is made more thorough, so that but little passes through the perforated partition 13' into the secondary chamber 2.

J represents a pipe adapted to conduct steam from the boiler to several jets or branches, J, entering the secondary combustion-chamher 2. Each of the branches J is surrounded by an annularair-passage, is, so that the steam,

as it enters the chamber 2, is mingled with air. The jets of mingled steam and air cause the combustion in the chamber 2 of carbon and gases passing unconsumed from the chamber 1, so-tliat but little unconsumed matter in the form of smoke, soot, or lamp-black passes to the smoke-stack. The oil is thus thoroughly utilized for the generation of steam, and little or no smoke is created.

The fire-box A. is provided with an ordinary coal-burning grate, so that coal can be used in the ordinary way.

The perforated partition Bis preferably composed of parallel pipes 9 p, connected at their upper and lower ends with water-chambers q g, which communicate with the boiler, the pipes p being separated by narrow openings or spaces, which constitute the perforations in the partition connecting the chamber lwith the chamber 2. The partition B therefore constitutes an improved water-table, which contains a large extent of surface exposed to the fire, and therefore'facilitates the heatingof the water in the boiler, besides protecting the ordinary flues, r, from the intense heat to which they would be subjected in case the partition or water-table were not provided,

tender.

t represents a pipe leading from the boiler to the oil-tank O, and adapted to conduct steam to the latter to warm the oil and preventitt'rom becoming staguantin cold weather. The pipe it should be of small size, so'that the steam admitted to the tank will not heat the oil to a dangerous extent.

The oil-pipes D, which are of metal, have metallic spiral sections D where they pass from the tender to the engine, to give said pipes the flexibility necessitated by the slight independent movements of the engine and The use of rubber connections between the engine and tender is thus avoided and a more durable substitute provided. I prefer to provide the steam-pip t with a similar spiral section, t.

I Having thus described my invention, I claim- Inthe herein-described furnace, the combination of a primary combustion-chamber, 1, a

secondary combustion-chamber, 2, the perforated wall or partition B, separatingsaid chambers, with the pipes D, D, E, and H for supplying hydrocarbon, steam, and air to the pri- 25 mary combustion-chamber to effect a violent combustion in said chamber, and the pipes J, J, and k for supplying steam and air to the secondary chamber and effecting the consumption of the unconsumed products passing 0 from theprimary chamber, the whole being constructed and arranged substantially as described.

In testimony whereoflhavesigned my name to this specification, in the presence of two 5 subscribing Witnesses, this 12th day of September, A. D. 1881.
